Hi,

I got the error:
Error (10482): VHDL error at aaa.vhd(13): object " list10x2" is used but not declared

Could anyone tell me what is wrong with this error since I get error at the declaration but it said the object is not declared?

Code:
library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;
use work.ioarrays.all;
library floatfixlib;
use floatfixlib.fixed_pkg.all; 




entity aaa is 


	port(
		


		pressure_in		 : in list10x2;--10 inputs, each inputs with 2 bits
}



Thank you

because the list10x2 is not a type defined in the packages you are using, or perhaps you didn't compile the packages before you started compilation of this file?

Try compiling the ioarrays package first.
